摘　　要：燃烧合成法制备的多孔Ti50Ni48Fe2形状记忆合金具有三维连通的孔隙结构,其平均孔隙尺寸约为350μm。采用化学法即酸液和碱液处理后在模拟体液中浸泡一定时间可在多孔形状记忆合金表面沉积出羟基磷灰石涂层.Porous Ti50Ni48Fe2 shape memory alloy fabricated by combustion synthesis was featured by interconnected three dimensionally pore structure with mean pore size of 350μm.Chemical method,i.e.acid-alkaline treatment followed by immersion in simulated body fluid for a period was performed to deposit hydroxyapatite coating on surface of porous shape memory alloy.
